“Blue Laws, Liquor Stores, and Crime"
This paper studies the relationship between crime and off-premise alcohol availability, looking at the repeal of Connecticut’s blue law banning the sale of retail alcohol on Sundays. Using detailed crime data in Hartford, I construct concentric rings around liquor stores to conduct a difference-in-differences analysis and find that allowing Sunday sales increased police incidents near retail alcohol stores by approximately 14%. This increase was mostly driven by alcohol-related and less-serious crimes. Additional results, using Providence, Rhode Island as a control, suggest that the repeal caused a net citywide increase. Moreover, there is no evidence that this increase was caused by a redistribution of criminal activity across other days of the week.Paper (pdf)
“Corporate Dentistry, Competition, and the Provision of Dental Care"
Examining the expansion of corporate dentistry, this paper analyzes the impact of dental support organizations (DSOs), commonly referred to as dental chains, on the provision of dental care and their strategic entry and exit into markets. Using a difference-in-differences design I find that the entry of DSO offices has a negligible but negative impact on the number of independent dentist offices. Moreover, using a pairwise maximum score estimator in a profit inequality design developed by Ellickson, Houghton and Timmins (2013), I am able to measure the effects of rival offices and local chain networks for a heterogeneous sample of DSOs.Paper (pdf) Code
“State Campaign Contributions from Shale Gas Development"
This paper analyzes firms’ strategic lobbying decisions in the context of unconventional upstream natural gas development in Pennsylvania. I construct an original dataset and describe patterns of state campaign contributions and state lobbying expenditures from shale gas operators. Lobbying seems to be the main strategy to influence the state government, and campaign contributions from these companies are relatively small and concentrated to legislative candidates running in districts that contain the majority of shale gas wells. Although previous campaign finance theories postulate that contributions aim to “buy policy" or “buy access" for lobbying, I find little evidence for either channel.Paper (pdf)
